1 '0 all whom it may concern: 7 I

Be it known that I, ARTHUR CLARKE SAR- 'cnANT, a citizen of the United States of America, residing at Agawam, in the county of Hampden and State of Massachusetts, have invented a new and useful Door-Stop, of'which the following is a specification,

My invention relates to devices for holding doors in open position, and consists'essentially of a fixed member carried by the;v door and" a movable member'supported from a member of the door frame or casing, both of special and peculiar construction, together with such'other parts and members as may be necessary or desirable in order to render the device'co'mplete' and serviceable, all as hereinafter set forth. 7

The primary object of my invention is to provide a stop, of the class described, which is applicable for use in connection with any swinging door at the top, where it is out of the way, and capableofsecuring the door when open andholding. the same in" such position, such stop being readily attached,

spring, or, in other words, with a door that is not self-closing. v 1 Other objects and advantages will appear in the course of theifollowing description;

I attain theob'jectsand secure the advantages of my invention by the means illus-] trated in the accompany ng drawings, in]

which V Figure l is a top' planof a practical form of my invention, the stop members being applied to a door casing and door, which latter is closed; Fig. 2, a front elevation of the parts and] members disposed as in the first view; Fig. 3, a front elevation of said parts and members, said door being open and under restraint'from the stop; Fig. 4, a side elevation of said door and stop as disposed in the preceding view, and as viewed from tl1ei-ighthand side of such view; Fig. 5, a similar side elevation, but showing the stopengaging members unlocked and about to be separated entirely by the closing of the door; Fig. 6, an enlarged, top plan of the stop member which is attached directly to the door; Fig, "7, an enlarged, bottom plan'of the swinging stop member, and, Fig. i

8, a detail in section of a bumper that may be used inthe event the door be not provided with self cloSing means. I

Similar reference characters designate similar parts throughout the several'views.

'In'the' general views fragmentary portions of ado'or jamb, a door lintel, and a .d oorare represented at 1,2, and 3, respectively. An arm 1 is secured by screws or otherwise to the underside of the lintel 2,

being let into said lintel in this case, and in order to show such arm in full and the top of thedoor 3'tl1e lintel, which isfover the attached end of said arm and over said door when closed, 'is' represente d' by broken lines in F ig. 1, so as to disclose in full the parts that otherwise would behidden. The jamb and lintel are both shown in section in Figs. 4L and 5. In the last view the fragment of the door 3 therein appearing is infsection,

A spring hinge of ordinary construction is represented at 5. This hinge, with its companion or companions which are not shown, supports the door 3 from the jamb 1, and hasa constant tendency to swing said door into closed position and hold it shut.

The stop comprises, with the arm 4, which isrigidly attached at its inner or rear end to'the lintel 2, as previously observed, a freely-suspended, swinging latch 6, at the forward end of said arm, and a si ves,

bracket having a lug 8, said bracket being rigidly attached, by screws or, other means, 7 to the inside of the door 3, or to the'side of;

said door which is adjacent to the arm. In addition to these parts and members, the arm 1 isprovided, back ofzthe latch 6, with a depending lug 9, and there is a bumper 1O 2 which projects from the same side of the door 8 to which the bracket 7 is secured.

The arm 4 has a vertical lug 11 at the outer or foremost end, which is flush with the outer edge of said arm, and the upper part or head of the latch 6 is pivotally con- 7 nected with Said lug by meansof a bolt 12 and a nut 13, a washer 14: being interposed between said latch head and the head of said bolt. latch 6 being through the center thereof and through the bolt 11,.said latch normally hangs vertically, and upon slightpressure or the application of very little force the latch is swung forwardly or rearwardly, to return to the vertical as soon as such pres-' sure or force is removed. I The lug 9 de- The center of gravity of the,

pends from the same edge of the arm 4 to which the latch 6 is contiguous;

The latch 6 has an arcuate, bottom edge 15, concentric with the bolt 11, and depending from such edge is a keeper 16. The keeper 16 extends obliquely across the central portion of the edge or bottom 15, from' the left-hand side forward and over to righthand side of suchbotto'm, and has a notch 11 in whatmay be termed its fi ont end. The sides of the keeper are slightly convex. One side (18) of the notch 17 is short and extends from the outer side of-the latch 6 or the outer, longitudinal edge of its bottom a short distance, and the other side (19) or said'hotch is longei and extends I forwardly, from saidffirst-named side,

toward the front end of I said latch "or or said bottom. I Preferably the sides 18 and l9 foi in ah hute a gle with each other. The oblique sides of the keeper 16 are designated by the numerals 20 and 21, the former extending fro'm'the front end of the notch side 19, ttatwarth a a inwardl to the inner side of the latch 6, where said' side 2O joins thereof, and said lug i is in plan a paral itlograih p ace said bracket with its ends (22%22) approximately right-anglesto the door 3, its sides (23 23) inclined inwardly toward the hinged tags of said oor The elevation (it the top of the 111g 8 is justlow enough to clear the latch bottom 15, when the door 3.

i is swungopen, and the relative location of said 111g s'uch'that at such time said lug is move thifough ah 'arc'iiate course which is intersected by the keeper 16, and conse; u'e'nt y encoiinters the latter, 7

heIlllg 9 is in the path of the bumper 10 when the door is opened. The bumper 10 is adjiistable in and out, for the reason 'presently to be given, and to that end said bumper may eo-nsist of a screw.

The operation of this door stop is described asfollows: I I I When the deer 3 is tnhd sufficiently wide, on and against the force of the spring hinge- 5, the outer side23 of the liig 8 encounters first the side 20 of the keeper 16,

and, by reasonof such contact and as said door continues to move, the latch 6 is caused to swing rearwardly on the holtor pivot 12 until said passes by the extreme front end of said keeper, when said latch swings forward by gravity and the contacting end,

1 on said lihrizontal part of which is now the rear end,of said lug is re ceived in the notch 17. The door is now re leased to the spring hinge 5, and at once causes the inner side 23 of the lug 8 to come into engagement with the side 19 of the notch 17- see Figs. 3 and 4. The door is thus held by the latch 6, through the medium of the lug 8, and prevented from closing.

A little care must be exercised in engaging the parts not to push the door open far enough to carry the lug 8 entirely beyond the keeper, or so far that, when the latch 6 s ing-s, forward, said lug will not be received in he notch 17. In the event this be done, however, it is necessary simply to manipulate the door in plained below for unlocking, and then bring about the locking action just as explained above. I f i I To unlock or release the door 3, push it open farther to cause the lug 8 to pass out of the notch 17 and beyond the keeper 16.

It is to be understood that, while the latch and lug are in locking engagement, the

former is disposed rearwardly so that it will swing forward as soon as thesame is released by the lug. The latch, therefore, swings forward and the parts are disposed as represented in-Fig; 5. Now permit the door to close. As the door swings toward its opening, the inner side 23 of the lug 8 ehcohhters the side 21 ofthe keeper 16 and crowds said keeper out of the way by causing the latch 6 t0 beswung forward'until the outer end 22 otsaid'lug passes clear oi said side 21 and said lug clear of said latch. The latch once assumes its normal position ih'rea'dihess to be engaged by the lug 8 and to lock the door the next time the same I is opened.

The primary purpose of the lug 9 and hamper 10 is to prot'eot'th'e latch 6 from the shock or strain that would be experienced thereby, in the absence of some such'means of pi oteeti'on, in the event the door 3 be opened v iolently or; pressed too hard against said lat'ch. To this end the bumper is set out only far 'en'oug just before the door reaches the latch 6, there being plenty ofble'ar'ance between said bumper and lug' to enable the lug 8 to becomeinterlocked with thfeke'eper 1 when said door opened, and to be released there;- from and swing clear thereof, when said door is swung inwardly to close it. I

Sometimes it is desired that the dOOr shall be unlocked by hand, or,,i'n other words, by manu' ally swinging the latch 6 rearwardly out of engagement with thelu'g 8; This result is obtained bysetti'ng the bumper 10 out far enough to encounter the lug 9 directly the lug 8 enters the notch 17, so that the do'o'r'can not be pushed open any farther or far enough to take said lug'out ,otsaid notch, and it becomes necessary to reach up to encounter the lug 9 the manner ex with the hand and swing said latch back in order to release the door. No spring is required in this case.

In the absence of spring hinges or equivalent elements, a resilient bumper may be employed, such as that illustrated in Fig. 8, for example. This bumper consists of a cap 25, which is provided with. a screw 26 for attachment to the door, a spiral spring 2. within such cap, and a pin 28 that'protrudes from said cap at the front end, and

has a head within said cap, against which said head bears.

The parts are so proportioned that, when the resilient bumper is substituted for the bumper 10, the pin 28 is forced inwardly, againstthe resiliency otthe spring 27, by means of the contact of said pin with the lug 9, when the lug 8 and the keeper 16 become engaged, and while such engagement lasts. The spring 27 has a tendency to swing the door in the direction to close it, just as do the spring-hinges, and so causes the lug 8 to be retained in contact with the side 19 of the notch 17, during the time of interlocking engagement of the parts.

The resilient bumper may, like the bumper l0, prevent the door 3 from coming into contact with the latch 6, and said firstnamed bumper may, also like said secondnamed bumper, be arranged so as to require that the door be unlocked by direct application of the hand to said latch.

The bottom of the keeper 16 is arcuate like the bottom of the latch 6 and concentric therewith, so that said latch can swing without binding on the horizontal part of the bracket 7.

More or less change in the shape, sir, construction, and arrangement of some all of the parts of the door stop ma made without departing from the spirit 0 m invention or exceeding the scope of what is claimed.

What I claim as my invention, and desire to secure by Letters Patent, is'-- 1. The combination, in a door stop, with lug carried by the door, of a swinging latch supported from a member 01"? the door casing, and provided onthe bottom with a notched keeper located normallyin the path of said lug, and adapted to be swung to permit said lug and the notched part of said keeper to become engaged, when said door is opened. I I

2. The combination, in a door stop, with a lug-carried by the door, of an arm supported from a member of the door frame, a latch pivotally connected with said arm and having on the bottom a notched keeper which is normally in the path ofsaid lug, the construction and arrangement of parts being such that, when said door is opened, said lug encounters said keeper and causes said latch to swing to permit said lug to l. The combination, in a door stop, with a braeketattached to the door and provided 1 with a vertical lug obliquelyarranged rela tive to said door, of a swinging latch supported from a member of the door frame, said latch having an obliquely arranged keeper which is normally in the path of 'saic lug, and is notched at one end to receive said lug.

5. The combination, in a door stop, with a lug carried by the door, of a swinging latch supported from a member of the door frame, said latch having a keeper which is normally in the path of said lug, such keeper being adapted, when encountered by said lug upon the opening of the door, tobe forcedout of the way and then to engage said lug and prevent said door from closing, and, upon the further opening of said door, to release said lug and assume a position that enables said lug to force said keeper out of the way when said door is moved to close.

6. In a door stop the combination with a latch carrying member adapted to be disposed at the top of a door frame, a freely swinging gravity latch depending therefrom, and a lu to be disposed on a door for engagement with the latch; of, an ear on said latch carrying member between the latch and door frame, a spring tension member to be disposed on the door for engage- 3 and the door frame, a spring tensioned posi-- tive stop member to be disposed on the door for engagement with saidv ear, said stop member being adjustable laterally of the door and the spring tension serving to maintain said latch and door lug in latched relation.
